Birger Schacht: Status update, January 2026

January was a slow month, I only did three uploads to Debian unstable: I was very happy to see the new dfsg-new-queue and that there are more hands now processing the NEW queue. I also finally got one of the packages accepted that I uploaded after the Trixie release: wayback which I uploaded last August. There has been another release since then, I ll try to upload that in the next few days. There was a bug report for carl asking for Windows support. carl used the xdg create for looking up the XDG directories, but xdg does not support windows systems (and it seems this will not change) The reporter also provided a PR to replace the dependency with the directories crate which more system agnostic. I adapted the PR a bit and merged it and released version 0.6.0 of carl. At my dayjob I refactored django-grouper. django-grouper is a package we use to find duplicate objects in our data. Our users often work with datasets of thousands of historical persons, places and institutions and in projects that run over years and ingest data from multiple sources, it happens that entries are created several times. I wrote the initial app in 2024, but was never really happy about the approach I used back then. It was based on this blog post that describes how to group spreadsheet text cells. It uses sklearns TfidfVectorizer with a custom analyzer and the library sparse_dot_topn for creating the matrix. All in all the module to calculate the clusters was 80 lines and with sparse_dot_topn it pulled in a rather niche Python library. I was pretty sure that this functionality could also be implemented with basic sklearn functionality and it was: we are now using DictVectorizer because in a Django app we are working with objects that can be mapped to dicts anyway. And for clustering the data, the app now uses the DBSCAN algorithm (with the manhattan distance as metric). The module is now only half the size and the whole app lost one dependency! I released those changes as version 0.3.0 of the app. At the end of January together with friends I went to Brussels to attend FOSDEM. We took the night train but there were a couple of broken down trains so the ride took 26 hours instead of one night. It is a good thing we had a one day buffer and FOSDEM only started on Saturday. As usual there were too many talks to visit, so I ll have to watch some of the recordings in the next few weeks. Some examples of talks I found interesting so far:

Matthias Geiger: Building a propagation box for oyster mushrooms

Inspiration In November I watched a short documentary about a guy who grew pearl oyster mushrooms in his backyard. They used pallet boxes (half of a europallet, 60x80x20 cm) as box to keep the substrate the mycelium feeds on in. Since I really enjoy (foraged) mushrooms and had the raw materials lying around, I opted to build it myself. This also had the benefit of using what was available and not just consuming, i.e. buying a pallet box. Preparing the raw materials I had 4.5 m x ~ 25 cm wooden spruce planks at home. My plan was to cut those into 2 m segments, then trim the edges down to 20 cm and then cut them into handy pieces, following the dimension of half a pallet box. This is what they looked after cutting them with an electric chainsaw to around 2 m: raw_planks You can see that the edges are still not straight, because that's how they came out of the sawmill. Once that was done I visited a family member that had a crosscut saw, a table saw and a band saw; all that I would need. First we trimmed the edges of the 2m planks with the table saw so they were somewhat straight; then they were flipped and the other edge was cut straight, and their width cut down to 20 cm. After moving them over to the crosscut saw dividing them into two 60 cm and one 80 cm was fairly easy. When cutting the 2m planks from the 4m ones I calculated with extra offcuts, so I got little waste overall and could use the whole length to get my desired board. This is what the cut pieces looked like: cut_planks Assembly I packed up my planks, now nicely cut to size, and I went to a hardware shop and bought hinges and screws. Assembly was fairly easy and fast: screw a hinge to a corner, hold the other plank onto the hinge so that the corners of both boards touch, and affix the hinge. plank_with_hinge corner_with_hinge When this was done, the frame looked like this: finished_frame As last step I drilled 10mm holes more or less random in the middle of the box. This is where the mushrooms will grow out of later and can be harvested. box_with_holes Closing thoughts This was a fun project I finished in a day. The hinges have the benefit that they allow the box to be folded up lenght-wise: folded This allows for convenient storage. Since it's too cold outside right now, cultivation will have to wait until spring. This also just needs mycelium one can just buy, and some material fungus digests. They can also be fed coffee grounds, and harvest of the fruit body is possible circa every two weeks.

Reproducible Builds: Reproducible Builds in December 2025

Welcome to the December 2025 from the Reproducible Builds project! Our monthly reports outline what we ve been up to over the past month, highlighting items of news from elsewhere in the increasingly-important area of software supply-chain security. As ever, if you are interested in contributing to the Reproducible Builds project, please see the Contribute page on our website.

  1. New orig-check service to validate Debian upstream tarballs
  2. Distribution work
  3. disorderfs updated to FUSE 3
  4. Mailing list updates
  5. Three new academic papers published
  6. Website updates
  7. Upstream patches

New orig-check service to validate Debian upstream tarballs This month, Debian Developer Lucas Nussbaum announced the orig-check service, which attempts to automatically reproduce the generation upstream tarballs (ie. the original source component of a Debian source package), comparing that to the upstream tarball actually shipped with Debian. As of the time of writing, it is possible for a Debian developer to upload a source archive that does not actually correspond to upstream s version. Whilst this is not inherently malicious (it typically indicates some tooling/process issue), the very possibility that a maintainer s version may differ potentially permits a maintainer to make (malicious) changes that would be misattributed to upstream. This service therefore nicely complements the whatsrc.org service, which was reported in our reports for both April and August. The orig-check is dedicated to Lunar, who sadly passed away a year ago.

Distribution work In Arch Linux this month, Robin Candau and Mark Hegreberg worked at making the Arch Linux WSL image bit-for-bit reproducible. Robin also shared some implementation details and future related work on our mailing list. Continuing a series reported in these reports for March, April and July 2025 (etc.), Simon Josefsson has published another interesting article this month, itself a followup to a post Simon published in December 2024 regarding GNU Guix Container Images that are hosted on GitLab. In Debian this month, Micha Lenk posted to the debian-backports-announce mailing list with the news that the Backports archive will now discard binaries generated and uploaded by maintainers: The benefit is that all binary packages [will] get built by the Debian buildds before we distribute them within the archive. Felix Moessbauer of Siemens then filed a bug in the Debian bug tracker to signal their intention to package debsbom, a software bill of materials (SBOM) generator for distributions based on Debian. This generated a discussion on the bug inquiring about the output format as well as a question about how these SBOMs might be distributed. Holger Levsen merged a number of significant changes written by Alper Nebi Yasak to the Debian Installer in order to improve its reproducibility. As noted in Alper s merge request, These are the reproducibility fixes I looked into before bookworm release, but was a bit afraid to send as it s just before the release, because the things like the xorriso conversion changes the content of the files to try to make them reproducible. In addition, 76 reviews of Debian packages were added, 8 were updated and 27 were removed this month adding to our knowledge about identified issues. A new different_package_content_when_built_with_nocheck issue type was added by Holger Levsen. [ ] Arnout Engelen posted to our mailing list reporting that they successfully reproduced the NixOS minimal installation ISO for the 25.11 release without relying on a pre-compiled package archive, with more details on their blog. Lastly, Bernhard M. Wiedemann posted another openSUSE monthly update for his work there.

disorderfs updated to FUSE 3 disorderfs is our FUSE-based filesystem that deliberately introduces non-determinism into system calls to reliably flush out reproducibility issues. This month, however, Roland Clobus upgraded disorderfs* from FUSE 2 to FUSE 3 after its package automatically got removed from Debian testing. Some tests in Debian currently require disorderfs to make the Debian live images reproducible, although disorderfs is not a Debian-specific tool.

Mailing list updates On our mailing list this month:
  • Luca Di Maio announced stampdalf, a filesystem timestamp preservation tool that wraps arbitrary commands and ensures filesystem timestamp reproducibility :
    stampdalf allows you to run any command that modifies files in a directory tree, then automatically resets all timestamps back to their original values. Any new files created during command execution are set to [the UNIX epoch] or a custom timestamp via SOURCE_DATE_EPOCH.
    The project s GitHub page helpfully reveals that the project is pronounced: stamp-dalf (stamp like time-stamp, dalf like Gandalf the wizard) as it s a wizard of time and stamps .)
  • Lastly, Reproducible Builds developer cen1 posted to our list announcing that early/experimental/alpha support for FreeBSD was added to rebuilderd. In their post, cen1 reports that the initial builds are in progress and look quite decent . cen1 also interestingly notes that since the upstream is currently not technically reproducible I had to relax the bit-for-bit identical requirement of rebuilderd [ ] I consider the pkg to be reproducible if the tar is content-identical (via diffoscope), ignoring timestamps and some of the manifest files. .

Three new academic papers published Yogya Gamage and Benoit Baudry of Universit de Montr al, Canada together with Deepika Tiwari and Martin Monperrus of KTH Royal Institute of Technology, Sweden published a paper on The Design Space of Lockfiles Across Package Managers:
Most package managers also generate a lockfile, which records the exact set of resolved dependency versions. Lockfiles are used to reduce build times; to verify the integrity of resolved packages; and to support build reproducibility across environments and time. Despite these beneficial features, developers often struggle with their maintenance, usage, and interpretation. In this study, we unveil the major challenges related to lockfiles, such that future researchers and engineers can address them. [ ]
A PDF of their paper is available online. Benoit Baudry also posted an announcement to our mailing list, which generated a number of replies.
Betul Gokkaya, Leonardo Aniello and Basel Halak of the University of Southampton then published a paper on the A taxonomy of attacks, mitigations and risk assessment strategies within the software supply chain:
While existing studies primarily focus on software supply chain attacks prevention and detection methods, there is a need for a broad overview of attacks and comprehensive risk assessment for software supply chain security. This study conducts a systematic literature review to fill this gap. By analyzing 96 papers published between 2015-2023, we identified 19 distinct SSC attacks, including 6 novel attacks highlighted in recent studies. Additionally, we developed 25 specific security controls and established a precisely mapped taxonomy that transparently links each control to one or more specific attacks. [ ]
A PDF of the paper is available online via the article s canonical page.
Aman Sharma and Martin Monperrus of the KTH Royal Institute of Technology, Sweden along with Benoit Baudry of Universit de Montr al, Canada published a paper this month on Causes and Canonicalization of Unreproducible Builds in Java. The abstract of the paper is as follows:
[Achieving] reproducibility at scale remains difficult, especially in Java, due to a range of non-deterministic factors and caveats in the build process. In this work, we focus on reproducibility in Java-based software, archetypal of enterprise applications. We introduce a conceptual framework for reproducible builds, we analyze a large dataset from Reproducible Central, and we develop a novel taxonomy of six root causes of unreproducibility. [ ]
A PDF of the paper is available online.

Website updates Once again, there were a number of improvements made to our website this month including:

Upstream patches The Reproducible Builds project detects, dissects and attempts to fix as many currently-unreproducible packages as possible. We endeavour to send all of our patches upstream where appropriate. This month, we wrote a large number of such patches, including:

Louis-Philippe V ronneau: 2025 A Musical Retrospective

2026 already! The winter weather here has really been beautiful and I always enjoy this time of year. Writing this yearly musical retrospective has now become a beloved tradition of mine1 and I enjoy retracing the year's various events through albums I listened to and concerts I went to. Albums In 2025, I added 141 new albums to my collection, around 60% more than last year's haul. I think this might have been too much? I feel like I didn't have time to properly enjoy all of them and as such, I decided to slow down my acquisition spree sometimes in early December, around the time I normally do the complete opposite. This year again, I bought the vast majority of my music on Bandcamp. Most of the other albums I bought as CDs and ripped them. Concerts In 2025, I went to the following 25 (!!) concerts: Although I haven't touched metalfinder's code in a good while, my instance still works very well and I get the occasional match when a big-name artist in my collection comes in town. Most the venues that advertise on Bandsintown are tied to Ticketmaster though, which means most underground artists (i.e. most of the music I listen to) end up playing elsewhere. As such, shout out again to the Gancio project and to the folks running the Montreal instance. It continues to be a smash hit and most of the interesting concerts end up being advertised there. See you all in 2026!

Dirk Eddelbuettel: BH 1.90.0-1 on CRAN: New Upstream

Boost Boost is a very large and comprehensive set of (peer-reviewed) libraries for the C++ programming language, containing well over one hundred individual libraries. The BH package provides a sizeable subset of header-only libraries for (easier, no linking required) use by R. It is fairly widely used: the (partial) CRAN mirror logs (aggregated from the cloud mirrors) show over 41.5 million package downloads. Version 1.90.0 of Boost was released a few days ago following the regular Boost release schedule of April, August and December releases. As before, we packaged it almost immediately and started testing following our annual update cycle which strives to balance being close enough to upstream and not stressing CRAN and the user base too much. The reverse depends check revealed only one really minor issue among the over three hundred direct reverse dependencies. And that issue was addressed yesterday within hours by a truly responsove maintainer (and it helped that a related issue had been addressed months earlier with version 1.89.). So big thanks to Jean-Romain Roussel for the prompt fix, and to Andrew Johnson for the earlier test with 1.89.0. As last year with 1.87.0, no new Boost libraries were added to BH so the (considerable) size is more or less unchanged. It lead to CRAN doing a manual inspection but as there were no other issues it sailed through as is now in the CRAN repository. The short NEWS entry follows.

Changes in version 1.90.0-1 (2025-12-13)
  • Upgrade to Boost 1.90.0, patched as usual to comment-out diagnostic suppression messages per the request of CRAN
  • Minor upgrades to continuous integration

Via my CRANberries, there is a diffstat report relative to the previous release. Comments and suggestions about BH are welcome via the issue tracker at the GitHub repo.

This post by Dirk Eddelbuettel originated on his Thinking inside the box blog. If you like this or other open-source work I do, you can now sponsor me at GitHub.

Iustin Pop: Yes, still alive!

Yeah, again three months have passed since my last (trivial) post, and I really don t know where the time has flown. I suppose the biggest problem was the long summer vacation, which threw me off-track, and then craziness started. Work work work, no time for anything, which kept me fully busy in August, and then you should travel . So mid-September I went on my first business trip since Covid, again to Kirkland, which in itself was awesome. Flew out Sunday, and as I was concerned I was going to lose too much fitness had a half-marathon planned on the weekend after the return I ran every morning of the four days I was there. And of course, on the last day, I woke up even earlier (05:30 AM), went out to run before sunrise, intending to do a very simple run along the road that borders the lake for 2.5K, then back . And right at the farthest point, a hundred metres before my goal of turning around, I tripped, started falling, and as I was falling, I hit sideways a metal pole. I was in a bus station, it was the pole that has the schedule at the top, and I hit it at relatively full speed, right across my left-side ribs. The crash took the entire air out of my lungs, and I don t remember if I ever felt pain/sensation like that I was seriously not able to breathe for 20 seconds or so, and I was wondering if I m going to pass out at this rate. Only 20 seconds, because my Garmin started howling like a police siren, and the screen was saying something along the lines of: Incident detected; contacting emergency services in 40 35 and I was fumbling to cancel that, since a) I wasn t that bad, b) notifying my wife that I had a crash would have not been a smart idea. My left leg was scraped in a few places, my left hand pretty badly, or more than just scraped, so my focus was on limping back, and finding a fountain to wash my injuries, which I did, so I kept running with blood dripping down my hand. Fun fun, everything was hurting, I took an Uber for the ~1Km to the office, had many meetings, took another Uber and flew back to Zurich. Seattle San Francisco Z rich, I think 14 hours, with my ribs hurting pretty badly. But I got home (Friday afternoon), and was wondering if I can run or not on Saturday. Saturday comes, I feel pretty OK, so I said let s try, will stop if the pain is too great. I pick up my number, I go to the start, of course in the last block and not my normal block, and I start running. After 50 metres, I knew this won t be good enough, but I said, let s make it to the first kilometre. Then to the first fuelling point, then to the first aid point, at which moment I felt good enough to go to the second one. Long story short, I ran the whole half marathon, with pain. Every stop for fuelling was mentally hard, as the pain stopped, and I knew I had to start running again, and the pain would resume. In the end, managed to finish: two and a half hours, instead of just two hours, but alive and very happy. Of course, I didn t know what was waiting for me Sunday I wake up in heavy pain, and despite painkillers, I was not feeling much better. The following night was terrible, Monday morning I went to the doctor, had X-rays, discussion with a radiologist. Not really broken, but more than just bruised. See this angle here? Bones don t have angles normally . Painkillers, chest/abdomen wrapping, no running! So my attempts to not lose fitness put me off running for a couple of weeks. Then October came, and I was getting better, but work was getting even more crazy. I don t know where November passed, honestly, and now we re already in December. I did manage to run, quite well, managed to bike a tiny bit and swim a little, but I m not in a place where I can keep a regular and consistent schedule. On the good side, I managed this year, for the first time since Covid, to not get sick. Hey, a sport injury is 100 better than a sickness, like I had in previous years, taking me out for two weeks. But life was crazy enough that I didn t read some of my email accounts for months, and I m just now starting to catch up to, well, baseline. Of course, the rib the lowest one on the left side is long-healed, or so I thought. After some strength training early this week, I was very sore the next day, and I wanted to test whether my rib is still sore. I touched it at the point , and it hurt so badly I couldn t believe. Two and a half months, and it s not done-done. And now it s just two weeks before Christmas and New Year s, and that time off will ruin my rhythm again. At least ski vacation is booked, ski service is done, and slowly, work is getting in good enough shape to actually enjoy thinking about vacation. So, in the end, a very adventurous last third of the year, and that wasn t even all. As I m writing this, my right wrist is bandaged and for the past 24 hours it hasn t hurt too much, but that s another, and not so interesting, story. I ll close with a yay for always being behind/backlogged, but alive and relatively well. My sport injuries are elective injuries so to speak, and I m very thankful for that. See you in the next post!

Russ Allbery: Review: The Last Soul Among Wolves

Review: The Last Soul Among Wolves, by Melissa Caruso
Series: The Echo Archives #2
Publisher: Orbit
Copyright: August 2025
ISBN: 0-316-30404-2
Format: Kindle
Pages: 355
The Last Soul Among Wolves is urban high fantasy with strong mystery vibes. It is a direct sequel to The Last Hour Between Worlds. You need the previous book for some character setup (and this book would spoil it badly), but you don't have to remember the first book in detail. Only the main plot outcomes are directly relevant and the characters will remind you of those. Kembrel Thorne is a Hound, the equivalent of a police detective in the medieval-inspired city setting of this series, but this book does not open with an official assignment. Instead, she has been dragged by her childhood friend Jaycel Morningrey as company for a reading of the will of old lady Lovegrace, reclusive owner of a gothic mansion on an island connected to the city by an intermittent sandbar. A surprise reunion with her gang of childhood friends ensues, followed by the revelation that they are all in serious trouble. Shortly after Kem left the group to become a Hound, the remaining four, plus several other apparently random people, got entangled with a powerful Echo artifact. Now that Lovegrace has died, one of them will inherit the artifact and the ability to make a wish, but only one. The rest will be killed at decreasing intervals until only the winner is left alive. The Last Hour Between Worlds was fae fantasy built around a problem that was more of a puzzle than a mystery. The Last Soul Among Wolves is closer to a classic mystery: A cast of characters are brought together and semi-isolated in a rural house, they start dying, and it's up to the detective to solve the mystery of their death before it's too late. In this case, the initial mechanism of death is supernatural and not in doubt the challenge instead is how to stop it from happening again but Kem's problems quickly become more complicated. As mystery plots go, this is more thriller than classical despite the setting. There are a few scenes of analyzing clues, but Kem is more likely to use the time-honored protagonist technique of throwing herself into danger and learning what's going on via the villain monologues. As readers of the previous book would expect, Rika Nonesuch is here too, hired by another of Kem's old friends, and the two navigate their personal feelings and the rivalry between their guilds in much the way that they did in the Last Hour Between Worlds. As in the first book, there is a sapphic romance subplot, but it's a very slow burn asexual romance. The best part of this series continues to be the world-building. The previous book introduced the idea of the Echoes and sent the characters exploring into stranger and stranger depths. This book fleshes out the rules in more detail, creating something that feels partly like a fae realm and partly like high fantasy involving gods, but diverges from both into a logic of its own. The ending satisfyingly passes my test of fantasy mysteries: Resolving the mystery requires understanding and applying the rules of the setting, which are sufficiently strange to create interesting outcomes but coherent enough that the reader doesn't feel like the author is cheating. There are some hissable villains here, but my favorite part of this book was the way Caruso added a lot of nuance and poignancy to the Echoes rather than showing them only as an uncanny threat. That choice made the world feel deeper and richer. It's not yet clear whether that element is setup for a longer-term series plot, but I hope Caruso will develop the story in that direction. It felt to me like Caruso is aiming for an ongoing series rather than a multi-volume story with a definite ending. She avoids a full episodic reset Rika, in particular, gets considerable character development and new complications that bode well for future volumes but it doesn't feel like the series is building towards an imminent climax. This is not a complaint. I enjoy these characters and this world and will happily keep devouring each new series entry. If you liked The Last Hour Between Worlds, I think you will like this. It doesn't have the same delight of initial discovery of the great world-building, but the plot is satisfying and a bit more complex and the supporting characters are even better than those in the first book. Once again, Caruso kept me turning the pages, and I'm now looking forward to a third volume. Recommended. The third book in the series has not yet been announced, but there are indications on social media that it is coming. Rating: 7 out of 10

Russ Allbery: Review: Politics on the Edge

Review: Politics on the Edge, by Rory Stewart
Publisher: Penguin Books
Copyright: 2023, 2025
Printing: 2025
ISBN: 979-8-217-06167-9
Format: Kindle
Pages: 429
Rory Stewart is a former British diplomat, non-profit executive, member of Parliament, and cabinet minister. Politics on the Edge is a memoir of his time in the UK Parliament from 2019 to 2019 as a Tory (Conservative) representing the Penrith and The Border constituency in northern England. It ends with his failed run against Boris Johnson for leader of the Conservative Party and Prime Minister. This book provoked many thoughts, only some of which are about the book. You may want to get a beverage; this review will be long. Since this is a memoir told in chronological order, a timeline may be useful. After Stewart's time as a regional governor in occupied Iraq (see The Prince of the Marshes), he moved to Kabul to found and run an NGO to preserve traditional Afghani arts and buildings (the Turquoise Mountain Foundation, about which I know nothing except what Stewart wrote in this book). By his telling, he found that work deeply rewarding but thought the same politicians who turned Iraq into a mess were going to do the same to Afghanistan. He started looking for ways to influence the politics more directly, which led him first to Harvard and then to stand for Parliament. The bulk of this book covers Stewart's time as MP for Penrith and The Border. The choice of constituency struck me as symbolic of Stewart's entire career: He was not a resident and had no real connection to the district, which he chose for political reasons and because it was the nearest viable constituency to his actual home in Scotland. But once he decided to run, he moved to the district and seems sincerely earnest in his desire to understand it and become part of its community. After five years as a backbencher, he joined David Cameron's government in a minor role as Minister of State in the Department for Environment, Food, and Rural Affairs. He then bounced through several minor cabinet positions (more on this later) before being elevated to Secretary of State for International Development under Theresa May. When May's government collapsed during the fight over the Brexit agreement, he launched a quixotic challenge to Boris Johnson for leader of the Conservative Party. I have enjoyed Rory Stewart's writing ever since The Places in Between. This book is no exception. Whatever one's other feelings about Stewart's politics (about which I'll have a great deal more to say), he's a talented memoir writer with an understated and contemplative style and a deft ability to shift from concrete description to philosophical debate without bogging down a story. Politics on the Edge is compelling reading at the prose level. I spent several afternoons happily engrossed in this book and had great difficulty putting it down. I find Stewart intriguing since, despite being a political conservative, he's neither a neoliberal nor any part of the new right. He is instead an apparently-sincere throwback to a conservatism based on epistemic humility, a veneration of rural life and long-standing traditions, and a deep commitment to the concept of public service. Some of his principles are baffling to me, and I think some of his political views are obvious nonsense, but there were several things that struck me throughout this book that I found admirable and depressingly rare in politics. First, Stewart seems to learn from his mistakes. This goes beyond admitting when he was wrong and appears to include a willingness to rethink entire philosophical positions based on new experience.
I had entered Iraq supporting the war on the grounds that we could at least produce a better society than Saddam Hussein's. It was one of the greatest mistakes in my life. We attempted to impose programmes made up by Washington think tanks, and reheated in air-conditioned palaces in Baghdad a new taxation system modelled on Hong Kong; a system of ministers borrowed from Singapore; and free ports, modelled on Dubai. But we did it ultimately at the point of a gun, and our resources, our abstract jargon and optimistic platitudes could not conceal how much Iraqis resented us, how much we were failing, and how humiliating and degrading our work had become. Our mission was a grotesque satire of every liberal aspiration for peace, growth and democracy.
This quote comes from the beginning of this book and is a sentiment Stewart already expressed in The Prince of the Marshes, but he appears to have taken this so seriously that it becomes a theme of his political career. He not only realized how wrong he was on Iraq, he abandoned the entire neoliberal nation-building project without abandoning his belief in the moral obligation of international aid. And he, I think correctly, identified a key source of the error: an ignorant, condescending superiority that dismissed the importance of deep expertise.
Neither they, nor indeed any of the 12,000 peacekeepers and policemen who had been posted to South Sudan from sixty nations, had spent a single night in a rural house, or could complete a sentence in Dinka, Nuer, Azande or Bande. And the international development strategy written jointly between the donor nations resembled a fading mission statement found in a new space colony, whose occupants had all been killed in an alien attack.
Second, Stewart sincerely likes ordinary people. This shone through The Places in Between and recurs here in his descriptions of his constituents. He has a profound appreciation for individual people who have spent their life learning some trade or skill, expresses thoughtful and observant appreciation for aspects of local culture, and appears to deeply appreciate time spent around people from wildly different social classes and cultures than his own. Every successful politician can at least fake gregariousness, and perhaps that's all Stewart is doing, but there is something specific and attentive about his descriptions of other people, including long before he decided to enter politics, that makes me think it goes deeper than political savvy. Third, Stewart has a visceral hatred of incompetence. I think this is the strongest through-line of his politics in this book: Jobs in government are serious, important work; they should be done competently and well; and if one is not capable of doing that, one should not be in government. Stewart himself strikes me as an insecure overachiever: fiercely ambitious, self-critical, a bit of a micromanager (I suspect he would be difficult to work for), but holding himself to high standards and appalled when others do not do the same. This book is scathing towards multiple politicians, particularly Boris Johnson whom Stewart clearly despises, but no one comes off worse than Liz Truss.
David Cameron, I was beginning to realise, had put in charge of environment, food and rural affairs a Secretary of State who openly rejected the idea of rural affairs and who had little interest in landscape, farmers or the environment. I was beginning to wonder whether he could have given her any role she was less suited to apart perhaps from making her Foreign Secretary. Still, I could also sense why Cameron was mesmerised by her. Her genius lay in exaggerated simplicity. Governing might be about critical thinking; but the new style of politics, of which she was a leading exponent, was not. If critical thinking required humility, this politics demanded absolute confidence: in place of reality, it offered untethered hope; instead of accuracy, vagueness. While critical thinking required scepticism, open-mindedness and an instinct for complexity, the new politics demanded loyalty, partisanship and slogans: not truth and reason but power and manipulation. If Liz Truss worried about the consequences of any of this for the way that government would work, she didn't reveal it.
And finally, Stewart has a deeply-held belief in state capacity and capability. He and I may disagree on the appropriate size and role of the government in society, but no one would be more disgusted by an intentional project to cripple government in order to shrink it than Stewart. One of his most-repeated criticisms of the UK political system in this book is the way the cabinet is formed. All ministers and secretaries come from members of Parliament and therefore branches of government are led by people with no relevant expertise. This is made worse by constant cabinet reshuffles that invalidate whatever small amounts of knowledge a minister was able to gain in nine months or a year in post. The center portion of this book records Stewart's time being shuffled from rural affairs to international development to Africa to prisons, with each move representing a complete reset of the political office and no transfer of knowledge whatsoever.
A month earlier, they had been anticipating every nuance of Minister Rogerson's diary, supporting him on shifts twenty-four hours a day, seven days a week. But it was already clear that there would be no pretence of a handover no explanation of my predecessor's strategy, and uncompleted initiatives. The arrival of a new minister was Groundhog Day. Dan Rogerson was not a ghost haunting my office, he was an absence, whose former existence was suggested only by the black plastic comb.
After each reshuffle, Stewart writes of trying to absorb briefings, do research, and learn enough about his new responsibilities to have the hope of making good decisions, while growing increasingly frustrated with the system and the lack of interest by most of his colleagues in doing the same. He wants government programs to be successful and believes success requires expertise and careful management by the politicians, not only by the civil servants, a position that to me both feels obviously correct and entirely at odds with politics as currently practiced. I found this a fascinating book to read during the accelerating collapse of neoliberalism in the US and, to judge by current polling results, the UK. I have a theory that the political press are so devoted to a simplistic left-right political axis based on seating arrangements during the French Revolution that they are missing a significant minority whose primary political motivation is contempt for arrogant incompetence. They could be convinced to vote for Sanders or Trump, for Polanski or Farage, but will never vote for Biden, Starmer, Romney, or Sunak. Such voters are incomprehensible to those who closely follow and debate policies because their hostile reaction to the center is not about policies. It's about lack of trust and a nebulous desire for justice. They've been promised technocratic competence and the invisible hand of market forces for most of their lives, and all of it looks like lies. Everyday living is more precarious, more frustrating, more abusive and dehumanizing, and more anxious, despite (or because of) this wholehearted embrace of economic "freedom." They're sick of every complaint about the increasing difficulty of life being met with accusations about their ability and work ethic, and of being forced to endure another round of austerity by people who then catch a helicopter ride to a party on some billionaire's yacht. Some of this is inherent in the deep structural weaknesses in neoliberal ideology, but this is worse than an ideological failure. The degree to which neoliberalism started as a project of sincere political thinkers is arguable, but that is clearly not true today. The elite class in politics and business is now thoroughly captured by people whose primary skill is the marginal manipulation of complex systems for their own power and benefit. They are less libertarian ideologues than narcissistic mediocrities. We are governed by management consultants. They are firmly convinced their organizational expertise is universal, and consider the specific business of the company, or government department, irrelevant. Given that context, I found Stewart's instinctive revulsion towards David Cameron quite revealing. Stewart, later in the book, tries to give Cameron some credit by citing several policy accomplishments and comparing him favorably to Boris Johnson (which, true, is a bar Cameron probably flops over). But I think Stewart's baffled astonishment at Cameron's vapidity says a great deal about how we have ended up where we are. This last quote is long, but I think it provides a good feel for Stewart's argument in this book.
But Cameron, who was rumoured to be sceptical about nation-building projects, only nodded, and then looking confidently up and down the table said, "Well, at least we all agree on one extremely straightforward and simple point, which is that our troops are doing very difficult and important work and we should all support them." It was an odd statement to make to civilians running humanitarian operations on the ground. I felt I should speak. "No, with respect, we do not agree with that. Insofar as we have focused on the troops, we have just been explaining that what the troops are doing is often futile, and in many cases making things worse." Two small red dots appeared on his cheeks. Then his face formed back into a smile. He thanked us, told us he was out of time, shook all our hands, and left the room. Later, I saw him repeat the same line in interviews: "the purpose of this visit is straightforward... it is to show support for what our troops are doing in Afghanistan". The line had been written, in London, I assumed, and tested on focus groups. But he wanted to convince himself it was also a position of principle. "David has decided," one of his aides explained, when I met him later, "that one cannot criticise a war when there are troops on the ground." "Why?" "Well... we have had that debate. But he feels it is a principle of British government." "But Churchill criticised the conduct of the Boer War; Pitt the war with America. Why can't he criticise wars?" "British soldiers are losing their lives in this war, and we can't suggest they have died in vain." "But more will die, if no one speaks up..." "It is a principle thing. And he has made his decision. For him and the party." "Does this apply to Iraq too?" "Yes. Again he understands what you are saying, but he voted to support the Iraq War, and troops are on the ground." "But surely he can say he's changed his mind?" The aide didn't answer, but instead concentrated on his food. "It is so difficult," he resumed, "to get any coverage of our trip." He paused again. "If David writes a column about Afghanistan, we will struggle to get it published." "But what would he say in an article anyway?" I asked. "We can talk about that later. But how do you get your articles on Afghanistan published?" I remembered how the US politicians and officials had shown their mastery of strategy and detail. I remembered the earnestness of Gordon Brown when I had briefed him on Iraq. Cameron seemed somehow less serious. I wrote as much in a column in the New York Times, saying that I was afraid the party of Churchill was becoming the party of Bertie Wooster.
I don't know Stewart's reputation in Britain, or in the constituency that he represented. I know he's been accused of being a self-aggrandizing publicity hound, and to some extent this is probably true. It's hard to find an ambitious politician who does not have that instinct. But whatever Stewart's flaws, he can, at least, defend his politics with more substance than a corporate motto. One gets the impression that he would respond favorably to demonstrated competence linked to a careful argument, even if he disagreed. Perhaps this is an illusion created by his writing, but even if so, it's a step in the right direction. When people become angry enough at a failing status quo, any option that promises radical change and punishment for the current incompetents will sound appealing. The default collapse is towards demagogues who are skilled at expressing anger and disgust and are willing to promise simple cures because they are indifferent to honesty. Much of the political establishment in the US, and possibly (to the small degree that I can analyze it from an occasional news article) in the UK, can identify the peril of the demagogue, but they have no solution other than a return to "politics as usual," represented by the amoral mediocrity of a McKinsey consultant. The rare politicians who seem to believe in something, who will argue for personal expertise and humility, who are disgusted by incompetence and have no patience for facile platitudes, are a breath of fresh air. There are a lot of policies on which Stewart and I would disagree, and perhaps some of his apparent humility is an affectation from the rhetorical world of the 1800s that he clearly wishes he were inhabiting, but he gives the strong impression of someone who would shoulder a responsibility and attempt to execute it with competence and attention to detail. He views government as a job, where coworkers should cooperate to achieve defined goals, rather than a reality TV show. The arc of this book, like the arc of current politics, is the victory of the reality TV show over the workplace, and the story of Stewart's run against Boris Johnson is hard reading because of it, but there's a portrayal here of a different attitude towards politics that I found deeply rewarding. If you liked Stewart's previous work, or if you want an inside look at parliamentary politics, highly recommended. I will be thinking about this book for a long time. Rating: 9 out of 10

Freexian Collaborators: Debian Contributions: Old Debian Printing software and C23, Work to decommission packages.qa.debian.org, rebootstrap uses *-for-host and more! (by Anupa Ann Joseph)

Debian Contributions: 2025-09 Contributing to Debian is part of Freexian s mission. This article covers the latest achievements of Freexian and their collaborators. All of this is made possible by organizations subscribing to our Long Term Support contracts and consulting services.

Updating old Debian Printing software to meet C23 requirements, by Thorsten Alteholz The work of Thorsten fell under the motto gcc15 . Due to the introduction of gcc15 in Debian, the default language version was changed to C23. This means that for example, function declarations without parameters are no longer allowed. As old software, which was created with ANSI C (or C89) syntax, made use of such function declarations, it was a busy month. One could have used something like -std=c17 as compile flags, but this would have just postponed the tasks. As a result Thorsten uploaded modernized versions of ink, nm2ppa and rlpr for the Debian printing team.

Work done to decommission packages.qa.debian.org, by Rapha l Hertzog Rapha l worked to decommission the old package tracking system (packages.qa.debian.org). After figuring out that it was still receiving emails from the bug tracking system (bugs.debian.org), from multiple debian lists and from some release team tools, he reached out to the respective teams to either drop those emails or adjust them so that they are sent to the current Debian Package Tracker (tracker.debian.org).

rebootstrap uses *-for-host, by Helmut Grohne Architecture cross bootstrapping is an ongoing effort that has shaped Debian in various ways over the years. A longer effort to express toolchain dependencies now bears fruit. When cross compiling, it becomes important to express what architecture one is compiling for in Build-Depends. As these packages have become available in trixie , more and more packages add this extra information and in August, the libtool package gained a gfortran-for-host dependency. It was the first package in the essential build closure to adopt this and required putting the pieces together in rebootstrap that now has to build gcc-defaults early on. There still are hundreds of packages whose dependencies need to be updated though.

Miscellaneous contributions
  • Rapha l dropped the Build Log Scan integration in tracker.debian.org since it was showing stale data for a while as the underlying service has been discontinued.
  • Emilio updated pixman to 0.46.4.
  • Emilio coordinated several transitions, and NMUed guestfs-tools to unblock one.
  • Stefano uploaded Python 3.14rc3 to Debian unstable. It s not yet used by any packages, but it allows testing the level of support in packages to begin.
  • Stefano upgraded almost all of the debian-social infrastructure to Debian trixie .
  • Stefano published the sponsorship brochures for DebConf 26.
  • Stefano attended the Debian Technical Committee meeting.
  • Stefano uploaded routine upstream updates for a handful of Python packages (pycparser, beautifulsoup4, platformdirs, pycparser, python-authlib, python-cffi, python-mitogen, python-resolvelib, python-super-collections, twine).
  • Stefano reviewed and responded to DebConf 25 feedback.
  • Stefano investigated and fixed a request visibility bug in debian-reimbursements (for admin-altered requests).
  • Lucas reviewed a couple of merge requests from external contributors for Go and Ruby packages.
  • Lucas updated some ruby packages to its latest upstream version (thin, passenger, and puma is still WIP).
  • Lucas set up the build environment to run rebuilds of reverse dependencies of ruby using ruby3.4. As an alternative, he is looking for personal repositories provided by Debusine to perform this task more easily. This is the preparation for the transition to ruby3.4 as the default in Debian.
  • Lucas helped on the next round of the Outreachy internship program.
  • Helmut sent patches for 30 cross build failures and responded to cross building support questions on the mailing list.
  • Helmut continued to maintain rebootstrap. As gcc version 15 became the default, test jobs for version 14 had to be dropped. A fair number of patches were applied to packages and could be dropped.
  • Helmut resumed removing RC-buggy packages from unstable and sponsored a termrec upload to avoid its deletion. This work was paused to give packages some time to migrate to forky .
  • Santiago reviewed different merge requests created by different contributors. Those MRs include a new test to build reverse dependencies, created by Aquila Macedo as part of his GSoC internship; restore how lintian was used in experimental, thanks Otto Kek l inen; and the fix by Christian Bayle to support again extra repositories in deb822-style sources, whose support was broken with the move to sbuild+unshare last month.
  • While doing some new upstream release updates, thanks to Debusine s reverse dependencies autopkgtest checks, Santiago discovered that paramiko 4.0 will introduce a regression in libcloud by the drop of support for the obsolete DSA keys. Santiago finally uploaded to unstable both paramiko 4.0, and a regression fix for libcloud.
  • Santiago has taken part in different discussions and meetings for the preparation of DebConf 26. The DebConf 26 local team aims to prepare for the conference with enough time in advance.
  • Carles kept working on the missing-package-relations and reporting missing Recommends. He improved the tooling to detect and report bugs creating 269 bugs and followed up comments. 37 bugs have been resolved, others acknowledged. The missing Recommends are a mixture of packages that are gone from Debian, packages that changed name, typos and also packages that were recommended but are not packaged in Debian.
  • Carles improved the missing-package-relations to report broken Suggests only for packages that used to be in Debian but are removed from it now. No bugs have been created yet for this case but identified 1320 of them.
  • Colin spent much of the month chasing down build/test regressions in various Python packages due to other upgrades, particularly relating to pydantic, python-pytest-asyncio, and rust-pyo3.
  • Colin optimized some code in ubuntu-dev-tools (affecting e.g. pull-debian-source) that made O(n) HTTP requests when it could instead make O(1).
  • Anupa published Micronews as part of Debian Publicity team work.

Registration is open until 20th September 2025, and we are very much looking forward to seeing many readers of these reports there!

Can t we have nice things? Debian Developer Gunnar Wolf blogged that George V. Neville-Neil s Kode Vicious column in Communications of the ACM in which reproducible builds is mentioned without needing to introduce it (assuming familiarity across the computing industry and academia) . Titled, Can t we have nice things?, the article mentions:
Once the proper measurement points are known, we want to constrain the system such that what it does is simple enough to understand and easy to repeat. It is quite telling that the push for software that enables reproducible builds only really took off after an embarrassing widespread security issue ended up affecting the entire Internet. That there had already been 50 years of software development before anyone thought that introducing a few constraints might be a good idea is, well, let s just say it generates many emotions, none of them happy, fuzzy ones. [ ]

Distribution work In Debian this month, Johannes Starosta filed a bug against the debian-repro-status package, reporting that it does not work on Debian trixie. (An upstream bug report was also filed.) Furthermore, 17 reviews of Debian packages were added, 10 were updated and 14 were removed this month adding to our knowledge about identified issues. In March s report, we included the news that Fedora would aim for 99% package reproducibility. This change has now been deferred to Fedora 44 according to Phoronix. Lastly, Bernhard M. Wiedemann posted another openSUSE monthly update for their work there.

Tool development diffoscope version 306 was uploaded to Debian unstable by Chris Lamb. It included contributions already covered in previous months as well as some changes by Zbigniew J drzejewski-Szmek to address issues with the fdtump support [ ] and to move away from the deprecated codes.open method. [ ][ ] strip-nondeterminism version 1.15.0-1 was uploaded to Debian unstable by Chris Lamb. It included a contribution by Matwey Kornilov to add support for inline archive files for Erlang s escript [ ]. kpcyrd has released a new version of rebuilderd. As a quick recap, rebuilderd is an automatic build scheduler that tracks binary packages available in a Linux distribution and attempts to compile the official binary packages from their (purported) source code and dependencies. The code for in-toto attestations has been reworked, and the instances now feature a new endpoint that can be queried to fetch the list of public-keys an instance currently identifies itself by. [ ] Lastly, Holger Levsen bumped the Standards-Version field of disorderfs, with no changes needed. [ ][ ]

Reproducibility testing framework The Reproducible Builds project operates a comprehensive testing framework running primarily at tests.reproducible-builds.org in order to check packages and other artifacts for reproducibility. In August, however, a number of changes were made by Holger Levsen, including:
  • Setting up six new rebuilderd workers with 16 cores and 16 GB RAM each.
  • reproduce.debian.net-related:
    • Do not expose pending jobs; they are confusing without explaination. [ ]
    • Add a link to v1 API specification. [ ]
    • Drop rebuilderd-worker.conf on a node. [ ]
    • Allow manual scheduling for any architectures. [ ]
    • Update path to trixie graphs. [ ]
    • Use the same rebuilder-debian.sh script for all hosts. [ ]
    • Add all other suites to all other archs. [ ][ ][ ][ ]
    • Update SSH host keys for new hosts. [ ]
    • Move to the pull184 branch. [ ][ ][ ][ ][ ]
    • Only allow 20 GB cache for workers. [ ]
  • OpenWrt-related:
    • Grant developer aparcar full sudo control on the ionos30 node. [ ][ ]
  • Jenkins nodes:
    • Add a number of new nodes. [ ][ ][ ][ ][ ]
    • Dont expect /srv/workspace to exist on OSUOSL nodes. [ ]
    • Stop hardcoding IP addresses in munin.conf. [ ]
    • Add maintenance and health check jobs for new nodes. [ ]
    • Document slight changes in IONOS resources usage. [ ]
  • Misc:
    • Drop disabled Alpine Linux tests for good. [ ]
    • Move Debian live builds and some other Debian builds to the ionos10 node. [ ]
    • Cleanup some legacy support from releases before Debian trixie. [ ]
In addition, Jochen Sprickerhof made the following changes relating to reproduce.debian.net:
  • Do not expose pending jobs on the main site. [ ]
  • Switch the frontpage to reference Debian forky [ ], but do not attempt to build Debian forky on the armel architecture [ ].
  • Use consistent and up to date rebuilder-debian.sh script. [ ]
  • Fix supported worker architectures. [ ]
  • Add a basic excuses page. [ ]
  • Move to the pull184 branch. [ ][ ][ ][ ]
  • Fix a typo in the JavaScript. [ ]
  • Update front page for the new v1 API. [ ][ ]
Lastly, Roland Clobus did some maintenance relating to the reproducibility testing of the Debian Live images. [ ][ ][ ][ ]

Upstream patches The Reproducible Builds project detects, dissects and attempts to fix as many currently-unreproducible packages as possible. We endeavour to send all of our patches upstream where appropriate. This month, we wrote a large number of such patches, including:

Birger Schacht: Status update, September 2025

Regarding Debian packaging this was a rather quiet month. I uploaded version 1.24.0-1 of foot and version 2.8.0-1 of git-quick-stats. I took the opportunity and started migrating my packages to the new version 5 watch file format, which I think is much more readable than the previous format. I also uploaded version 0.1.1-1 of libscfg to NEW. libscfg is a C implementation of the scfg configuration file format and it is a dependency of recent version of kanshi. kanshi is a tool similar to autorandr which allows you define output profiles and kanshi switches to the correct output profile on hotplug events. Once libscfg is in unstable I can finally update kanshi to the latest version. A lot of time this month in finalizing a redesign of the output rendering of carl. carl is a small rust program I wrote that provides a calendar view similar to cal, but it comes with colors and ical file integration. That means that you can not only display a simple calendar, but also colorize/highlight dates based on various attributes or based on events on that day. In the initial versions of carl the output rendering was simply hardcoded into the app.
Screenshot of carl
This was a bit cumbersome to maintain and not configurable for users. I am using templating languages on a daily basis, so I decided I would reimplement the output generation of carl to use templates. I chose the minijinja Rust library which is based on the syntax and behavior of the Jinja2 template engine for Python . There are others out there, like tera, but minijinja seems to be more active in development currently. I worked on this implementation on and off for the last year and finally had the time to finish it up and write some additional tests for the outputs. It is easier to maintain templates than Rust code that uses write!() to format the output. I also implemented a configuration option for users to override the templates. Additional to the output refactoring I also fixed couple of bugs and finally released v0.4.0 of carl. In my dayjob I released version 0.53 of apis-core-rdf which contains the place lookup field which I implemented in August. A couple of weeks later we released version 0.54 which comes with a middleware to show pass on messages from the Django messages framework via response header to HTMX to trigger message popups. This implementation is based on the blog post Using the Django messages framework with HTMX. Version 0.55 was the last release in September. It contained preparations for refactoring the import logic as well as a couple of UX improvements.

Vincent Bernat: Akvorado release 2.0

Akvorado 2.0 was released today! Akvorado collects network flows with IPFIX and sFlow. It enriches flows and stores them in a ClickHouse database. Users can browse the data through a web console. This release introduces an important architectural change and other smaller improvements. Let s dive in!
$ git diff --shortstat v1.11.5
 493 files changed, 25015 insertions(+), 21135 deletions(-)

New outlet service The major change in Akvorado 2.0 is splitting the inlet service into two parts: the inlet and the outlet. Previously, the inlet handled all flow processing: receiving, decoding, and enrichment. Flows were then sent to Kafka for storage in ClickHouse:
Akvorado flow processing before the change: flows are received and processed by the inlet, sent to Kafka and stored in ClickHouse
Akvorado flow processing before the introduction of the outlet service
Network flows reach the inlet service using UDP, an unreliable protocol. The inlet must process them fast enough to avoid losing packets. To handle a high number of flows, the inlet spawns several sets of workers to receive flows, fetch metadata, and assemble enriched flows for Kafka. Many configuration options existed for scaling, which increased complexity for users. The code needed to avoid blocking at any cost, making the processing pipeline complex and sometimes unreliable, particularly the BMP receiver.1 Adding new features became difficult without making the problem worse.2 In Akvorado 2.0, the inlet receives flows and pushes them to Kafka without decoding them. The new outlet service handles the remaining tasks:
Akvorado flow processing after the change: flows are received by the inlet, sent to Kafka, processed by the outlet and inserted in ClickHouse
Akvorado flow processing after the introduction of the outlet service
This change goes beyond a simple split:3 the outlet now reads flows from Kafka and pushes them to ClickHouse, two tasks that Akvorado did not handle before. Flows are heavily batched to increase efficiency and reduce the load on ClickHouse using ch-go, a low-level Go client for ClickHouse. When batches are too small, asynchronous inserts are used (e20645). The number of outlet workers scales dynamically (e5a625) based on the target batch size and latency (50,000 flows and 5 seconds by default). This new architecture also allows us to simplify and optimize the code. The outlet fetches metadata synchronously (e20645). The BMP component becomes simpler by removing cooperative multitasking (3b9486). Reusing the same RawFlow object to decode protobuf-encoded flows from Kafka reduces pressure on the garbage collector (8b580f). The effect on Akvorado s overall performance was somewhat uncertain, but a user reported 35% lower CPU usage after migrating from the previous version, plus resolution of the long-standing BMP component issue.

Other changes This new version includes many miscellaneous changes, such as completion for source and destination ports (f92d2e), and automatic restart of the orchestrator service (0f72ff) when configuration changes to avoid a common pitfall for newcomers. Let s focus on some key areas for this release: observability, documentation, CI, Docker, Go, and JavaScript.

Observability Akvorado exposes metrics to provide visibility into the processing pipeline and help troubleshoot issues. These are available through Prometheus HTTP metrics endpoints, such as /api/v0/inlet/metrics. With the introduction of the outlet, many metrics moved. Some were also renamed (4c0b15) to match Prometheus best practices. Kafka consumer lag was added as a new metric (e3a778). If you do not have your own observability stack, the Docker Compose setup shipped with Akvorado provides one. You can enable it by activating the profiles introduced for this purpose (529a8f). The prometheus profile ships Prometheus to store metrics and Alloy to collect them (2b3c46, f81299, and 8eb7cd). Redis and Kafka metrics are collected through the exporter bundled with Alloy (560113). Other metrics are exposed using Prometheus metrics endpoints and are automatically fetched by Alloy with the help of some Docker labels, similar to what is done to configure Traefik. cAdvisor was also added (83d855) to provide some container-related metrics. The loki profile ships Loki to store logs (45c684). While Alloy can collect and ship logs to Loki, its parsing abilities are limited: I could not find a way to preserve all metadata associated with structured logs produced by many applications, including Akvorado. Vector replaces Alloy (95e201) and features a domain-specific language, VRL, to transform logs. Annoyingly, Vector currently cannot retrieve Docker logs from before it was started. Finally, the grafana profile ships Grafana, but the shipped dashboards are broken. This is planned for a future version.

Documentation The Docker Compose setup provided by Akvorado makes it easy to get the web interface up and running quickly. However, Akvorado requires a few mandatory steps to be functional. It ships with comprehensive documentation, including a chapter about troubleshooting problems. I hoped this documentation would reduce the support burden. It is difficult to know if it works. Happy users rarely report their success, while some users open discussions asking for help without reading much of the documentation. In this release, the documentation was significantly improved.
$ git diff --shortstat v1.11.5 -- console/data/docs
 10 files changed, 1873 insertions(+), 1203 deletions(-)
The documentation was updated (fc1028) to match Akvorado s new architecture. The troubleshooting section was rewritten (17a272). Instructions on how to improve ClickHouse performance when upgrading from versions earlier than 1.10.0 was added (5f1e9a). An LLM proofread the entire content (06e3f3). Developer-focused documentation was also improved (548bbb, e41bae, and 871fc5). From a usability perspective, table of content sections are now collapsable (c142e5). Admonitions help draw user attention to important points (8ac894).

End-to-end tests (883e19) ensure the shipped Docker Compose setup works as expected. Hurl runs tests on various HTTP endpoints, particularly to verify metrics (42679b and 169fa9). For example:
## Test inlet has received NetFlow flows
GET http://127.0.0.1:8080/prometheus/api/v1/query
[Query]
query: sum(akvorado_inlet_flow_input_udp_packets_total job="akvorado-inlet",listener=":2055" )

Docker Akvorado ships with a comprehensive Docker Compose setup to help users get started quickly. It ensures a consistent deployment, eliminating many configuration-related issues. It also serves as a living documentation of the complete architecture. This release brings some small enhancements around Docker: Previously, many Docker images were pulled from the Bitnami Containers library. However, VMWare acquired Bitnami in 2019 and Broadcom acquired VMWare in 2023. As a result, Bitnami images were deprecated in less than a month. This was not really a surprise4. Previous versions of Akvorado had already started moving away from them. In this release, the Apache project s Kafka image replaces the Bitnami one (1eb382). Thanks to the switch to KRaft mode, Zookeeper is no longer needed (0a2ea1, 8a49ca, and f65d20). Akvorado s Docker images were previously compiled with Nix. However, building AArch64 images on x86-64 is slow because it relies on QEMU userland emulation. The updated Dockerfile uses multi-stage and multi-platform builds: one stage builds the JavaScript part on the host platform, one stage builds the Go part cross-compiled on the host platform, and the final stage assembles the image on top of a slim distroless image (268e95 and d526ca).

When building for multiple platforms with --platform linux/amd64,linux/arm64,linux/arm/v7, the build steps until the highlighted line execute only once for all platforms. This significantly speeds up the build. Akvorado now ships Docker images for these platforms: linux/amd64, linux/amd64/v3, linux/arm64, and linux/arm/v7. When requesting ghcr.io/akvorado/akvorado, Docker selects the best image for the current CPU. On x86-64, there are two choices. If your CPU is recent enough, Docker downloads linux/amd64/v3. This version contains additional optimizations and should run faster than the linux/amd64 version. It would be interesting to ship an image for linux/arm64/v8.2, but Docker does not support the same mechanism for AArch64 yet (792808).

Go This release includes many changes related to Go but not visible to the users.

Toolchain In the past, Akvorado supported the two latest Go versions, preventing immediate use of the latest enhancements. The goal was to allow users of stable distributions to use Go versions shipped with their distribution to compile Akvorado. However, this became frustrating when interesting features, like go tool, were released. Akvorado 2.0 requires Go 1.25 (77306d) but can be compiled with older toolchains by automatically downloading a newer one (94fb1c).5 Users can still override GOTOOLCHAIN to revert this decision. The recommended toolchain updates weekly through CI to ensure we get the latest minor release (5b11ec). This change also simplifies updates to newer versions: only go.mod needs updating. Thanks to this change, Akvorado now uses wg.Go() (77306d) and I have started converting some unit tests to the new test/synctest package (bd787e, 7016d8, and 159085).

Testing When testing equality, I use a helper function Diff() to display the differences when it fails:
got := input.Keys()
expected := []int 1, 2, 3 
if diff := helpers.Diff(got, expected); diff != ""  
    t.Fatalf("Keys() (-got, +want):\n%s", diff)
 
This function uses kylelemons/godebug. This package is no longer maintained and has some shortcomings: for example, by default, it does not compare struct private fields, which may cause unexpectedly successful tests. I replaced it with google/go-cmp, which is stricter and has better output (e2f1df).

Another package for Kafka Another change is the switch from Sarama to franz-go to interact with Kafka (756e4a and 2d26c5). The main motivation for this change is to get a better concurrency model. Sarama heavily relies on channels and it is difficult to understand the lifecycle of an object handed to this package. franz-go uses a more modern approach with callbacks6 that is both more performant and easier to understand. It also ships with a package to spawn fake Kafka broker clusters, which is more convenient than the mocking functions provided by Sarama.

Improved routing table for BMP To store its routing table, the BMP component used kentik/patricia, an implementation of a patricia tree focused on reducing garbage collection pressure. gaissmai/bart is a more recent alternative using an adaptation of [Donald Knuth s ART algorithm][] that promises better performance and delivers it: 90% faster lookups and 27% faster insertions (92ee2e and fdb65c). Unlike kentik/patricia, gaissmai/bart does not help efficiently store values attached to each prefix. I adapted the same approach as kentik/patricia to store route lists for each prefix: store a 32-bit index for each prefix, and use it to build a 64-bit index for looking up routes in a map. This leverages Go s efficient map structure. gaissmai/bart also supports a lockless routing table version, but this is not simple because we would need to extend this to the map storing the routes and to the interning mechanism. I also attempted to use Go s new unique package to replace the intern package included in Akvorado, but performance was worse.7

Miscellaneous Previous versions of Akvorado were using a custom Protobuf encoder for performance and flexibility. With the introduction of the outlet service, Akvorado only needs a simple static schema, so this code was removed. However, it is possible to enhance performance with planetscale/vtprotobuf (e49a74, and 8b580f). Moreover, the dependency on protoc, a C++ program, was somewhat annoying. Therefore, Akvorado now uses buf, written in Go, to convert a Protobuf schema into Go code (f4c879). Another small optimization to reduce the size of the Akvorado binary by 10 MB was to compress the static assets embedded in Akvorado in a ZIP file. It includes the ASN database, as well as the SVG images for the documentation. A small layer of code makes this change transparent (b1d638 and e69b91).

JavaScript Recently, two large supply-chain attacks hit the JavaScript ecosystem: one affecting the popular packages chalk and debug and another impacting the popular package @ctrl/tinycolor. These attacks also exist in other ecosystems, but JavaScript is a prime target due to heavy use of small third-party dependencies. The previous version of Akvorado relied on 653 dependencies. npm-run-all was removed (3424e8, 132 dependencies). patch-package was removed (625805 and e85ff0, 69 dependencies) by moving missing TypeScript definitions to env.d.ts. eslint was replaced with oxlint, a linter written in Rust (97fd8c, 125 dependencies, including the plugins). I switched from npm to Pnpm, an alternative package manager (fce383). Pnpm does not run install scripts by default8 and prevents installing packages that are too recent. It is also significantly faster.9 Node.js does not ship Pnpm but it ships Corepack, which allows us to use Pnpm without installing it. Pnpm can also list licenses used by each dependency, removing the need for license-compliance (a35ca8, 42 dependencies). For additional speed improvements, beyond switching to Pnpm and Oxlint, Vite was replaced with its faster Rolldown version (463827). After these changes, Akvorado only pulls 225 dependencies.

Next steps I would like to land three features in the next version of Akvorado:
  • Add Grafana dashboards to complete the observability stack. See issue #1906 for details.
  • Integrate OVH s Grafana plugin by providing a stable API for such integrations. Akvorado s web console would still be useful for browsing results, but if you want to build and share dashboards, you should switch to Grafana. See issue #1895.
  • Move some work currently done in ClickHouse (custom dictionaries, GeoIP and IP enrichment) back into the outlet service. This should give more flexibility for adding features like the one requested in issue #1030. See issue #2006.

I started working on splitting the inlet into two parts more than one year ago. I found more motivation in recent months, partly thanks to Claude Code, which I used as a rubber duck. Almost none of the produced code was kept:10 it is like an intern who does not learn.

  1. Many attempts were made to make the BMP component both performant and not blocking. See for example PR #254, PR #255, and PR #278. Despite these efforts, this component remained problematic for most users. See issue #1461 as an example.
  2. Some features have been pushed to ClickHouse to avoid the processing cost in the inlet. See for example PR #1059.
  3. This is the biggest commit:
    $ git show --shortstat ac68c5970e2c   tail -1
    231 files changed, 6474 insertions(+), 3877 deletions(-)
    
  4. Broadcom is known for its user-hostile moves. Look at what happened with VMWare.
  5. As a Debian developer, I dislike these mechanisms that circumvent the distribution package manager. The final straw came when Go 1.25 spent one month in the Debian NEW queue, an arbitrary mechanism I don t like at all.
  6. In the early years of Go, channels were heavily promoted. Sarama was designed during this period. A few years later, a more nuanced approach emerged. See notably Go channels are bad and you should feel bad.
  7. This should be investigated further, but my theory is that the intern package uses 32-bit integers, while unique uses 64-bit pointers. See commit 74e5ac.
  8. This is also possible with npm. See commit dab2f7.
  9. An even faster alternative is Bun, but it is less available.
  10. The exceptions are part of the code for the admonition blocks, the code for collapsing the table of content, and part of the documentation.

Joey Hess: cheap DIY solar fence design

A year ago I installed a 4 kilowatt solar fence. I'm revisiting it this Sun Day, to share the design, now that I have prooved it out.
The solar fence and some other ground and pole mount solar panels, seen through leaves.
Solar fencing manufacturers have some good simple designs, but it's hard to buy for a small installation. They are selling to utility scale solar mostly. And those are installed by driving metal beams into the ground, which requires heavy machinery. Since I have experience with Ironridge rails for roof mount solar, I decided to adapt that system for a vertical mount. Which is something it was not designed for. I combined the Ironridge hardware with regular parts from the hardware store. The cost of mounting solar panels nowadays is often higher than the cost of the panels. I hoped to match the cost, and I nearly did. The solar panels cost $100 each, and the fence cost $110 per solar panel. This fence was significantly cheaper than conventional ground mount arrays that I considered as alternatives, and made a better use of a difficult hillside location. I used 7 foot long Ironridge XR-10 rails, which fit 2 solar panels per rail. (Longer rails would need a center post anyway, and the 7 foot long rails have cheaper shipping, since they do not need to be shipped freight.) For the fence posts, I used regular 4x4" treated posts. 12 foot long, set in 3 foot deep post holes, with 3x 50 lb bags of concrete per hole and 6 inches of gravel on the bottom.
detail of how the rails are mounted to the posts, and the panels to the rails
To connect the Ironridge rails to the fence posts, I used the Ironridge LFT-03-M1 slotted L-foot bracket. Screwed into the post with a 5/8 x 3 inch hot-dipped galvanized lag screw. Since a treated post can react badly with an aluminum bracket, there needs to be some flashing between the post and bracket. I used Shurtape PW-100 tape for that. I see no sign of corrosion after 1 year. The rest of the Ironridge system is a T-bolt that connects the rail to the L-foot (part BHW-SQ-02-A1), and Ironridge solar panel fasteners (UFO-CL-01-A1 and UFO-STP-40MM-M1). Also XR-10 end caps and wire clips. Since the Ironridge hardware is not designed to hold a solar panel at a 90 degree angle, I was concerned that the panels might slide downward over time. To help prevent that, I added some additional support brackets under the bottom of the panels. So far, that does not seem to have been a problem though. I installed Aptos 370 watt solar panels on the fence. They are bifacial, and while the posts block the back partially, there is still bifacial gain on cloudy days. I left enough space under the solar panels to be able to run a push mower under them.
Me standing in front of the solar fence at end of construction
I put pairs of posts next to one-another, so each 7 foot segment of fence had its own 2 posts. This is the least elegant part of this design, but fitting 2 brackets next to one-another on a single post isn't feasible. I bolted the pairs of posts together with some spacers. A side benefit of doing it this way is that treated lumber can warp as it dries, and this prevented much twisting of the posts. Using separate posts for each segment also means that the fence can traverse a hill easily. And it does not need to be perfectly straight. In fact, my fence has a 30 degree bend in the middle. This means it has both south facing and south-west facing panels, so can catch the light for longer during the day. After building the fence, I noticed there was a slight bit of sway at the top, since 9 feet of wooden post is not entirely rigid. My worry was that a gusty wind could rattle the solar panels. While I did not actually observe that happening, I added some diagonal back bracing for peace of mind.

Inspecting the fence today, I find no problems after the first year. I hope it will last 30 years, with the lifespan of the treated lumber being the likely determining factor. As part of my larger (and still ongoing) ground mount solar install, the solar fence has consistently provided great power. The vertical orientation works well at latitude 36. It also turned out that the back of the fence was useful to hang conduit and wiring and solar equipment, and so it turned into the electrical backbone of my whole solar field. But that's another story.. solar fence parts list

Bits from Debian: Bits From Argentina - August 2025

DebConf26 is already in the air in Argentina. Organizing DebConf26 give us the opportunity to talk about Debian in our country again. This is not the first time that Debian has come here, previously Argentina has hosted DebConf 8 in Mar del Plata. In August, Nattie Mayer-Hutchings and Stefano Rivera from DebConf Committee visited the venue where the next DebConf will take place. They came to Argentina in order to see what it is like to travel from Buenos Aires to Santa Fe (the venue of the next DebConf). In addition, they were able to observe the layout and size of the classrooms and halls, as well as the infrastructure available at the venue, which will be useful for the Video Team. But before going to Santa Fe, on the August 27th, we organized a meetup in Buenos Aires at GCoop, where we hosted some talks: GCoop Talks On August 28th, we had the opportunity to get to know the Venue. We walked around the city and, obviously, sampled some of the beers from Santa Fe. On August 29th we met with representatives of the University and local government who were all very supportive. We are very grateful to them for opening their doors to DebConf. UNL Meeting In the afternoon we met some of the local free software community at an event we held in ATE Santa Fe. The event included several talks: ATE Talks Thanks to Debian Argentina, and all the people who will make DebConf26 possible. Thanks to Nattie Mayer-Hutchings and Stefano Rivera for reviewing an earlier version of this article.

Freexian Collaborators: Debian Contributions: Preparing for setup.py install deprecation, Salsa CI, Debian 13 "trixie" release and more! (by Anupa Ann Joseph)

Debian Contributions: 2025-08 Contributing to Debian is part of Freexian s mission. This article covers the latest achievements of Freexian and their collaborators. All of this is made possible by organizations subscribing to our Long Term Support contracts and consulting services.

Preparing for setup.py install deprecation, by Colin Watson setuptools upstream will be removing the setup.py install command on 31 October. While this may not trickle down immediately into Debian, it does mean that in the near future nearly all Python packages will have to use pybuild-plugin-pyproject (though they don t necessarily have to use pyproject.toml; this is just a question of how the packaging runs the build system). Some of the Python team talked about this a bit at DebConf, and Colin volunteered to write up some notes on cases where this isn t straightforward. This page will likely grow as the team works on this problem.

Salsa CI, by Santiago Ruano Rinc n Santiago fixed some pending issues in the MR that moves the pipeline to sbuild+unshare, and after several months, Santiago was able to mark the MR as ready. Part of the recent fixes include handling external repositories, honoring the RELEASE autodetection from d/changelog (thanks to Ahmed Siam for spotting the main reason of the issue), and fixing a regression about the apt resolver for *-backports releases. Santiago is currently waiting for a final review and approval from other members of the Salsa CI team, and being able to merge it. Thanks to all the folks who have helped testing the changes or provided feedback so far. If you want to test the current MR, you need to include the following pipeline definition in your project s CI config file:
---
include:
  - https://salsa.debian.org/santiago/pipeline/raw/sbuild-unshare-02-salsa-ci/salsa-ci.yml
  - https://salsa.debian.org/santiago/pipeline/raw/sbuild-unshare-02-salsa-ci/pipeline-jobs.yml
As a reminder, this MR will make the Salsa CI pipeline build the packages more similar to how it s built by the Debian official builders. This will also save some resources, since the default pipeline will have one stage less (the provisioning) stage, and will make it possible for more projects to be built on salsa.debian.org (including large projects and those from the OCaml ecosystem), etc. See the different issues being fixed in the MR description.

Debian 13 trixie release, by Emilio Pozuelo Monfort On August 9th, Debian 13 trixie was released, building on two years worth of updates and bug fixes from hundreds of developers. Emilio helped coordinate the release, communicating with several teams involved in the process.

DebConf 26 Site Visit, by Stefano Rivera Stefano visited Santa Fe, Argentina, the site for DebConf 26 next year. The aim of the visit was to help build a local team and see the conference venue first-hand. Stefano and Nattie represented the DebConf Committee. The local team organized Debian meetups in Buenos Aires and Santa Fe, where Stefano presented a talk on Debian and DebConf. Venues were scouted and the team met with the university management and local authorities.

Miscellaneous contributions
  • Rapha l updated tracker.debian.org after the trixie release to add the new forky release in the set of monitored distributions. He also reviewed and deployed the work of Scott Talbert showing open merge requests from salsa in the action needed panel.
  • Rapha l reviewed some DEP-3 changes to modernize the embedded examples in light of the broad git adoption.
  • Rapha l configured new workflows on debusine.debian.net to upload to trixie and trixie-security, and officially announced the service on debian-devel-announce, inviting Debian developers to try the service for their next upload to unstable.
  • Carles created a merge request for django-compressor upstream to fix an error when concurrent node processing happened. This will allow removing a workaround added in openstack-dashboard and avoid the same bug in other projects that use django-compressor.
  • Carles prepared a system to detect packages that Recommends packages which don t exist in unstable. Processed (either reported or ignored due to mis-detected problems or temporary problems) 16% of the reports. Will continue next month.
  • Carles got familiar and gave feedback for the freedict-wikdict package. Planned contributions with the maintainer to improve the package.
  • Helmut responded to queries related to /usr-move.
  • Helmut adapted crossqa.d.n to the release of trixie .
  • Helmut diagnosed sufficient failures in rebootstrap to make it work with gcc-15.
  • Helmut fixed the CI pipeline of debvm.
  • Helmut sent patches for 19 cross build problems.
  • Faidon discovered that the Multi-Arch hinter would emit confusing hints about :any annotations. Helmut identified the root cause to be the handling of virtual packages and fixed it.
  • Enrico took some dust off python-debiancontributors and prototyped a receiving end for salsa webpings, to start followup work to contributors.debian.org discussions at DebConf25.
  • Colin upgraded about 70 Python packages to new upstream versions, which is around 10% of the backlog; this included a complicated Pydantic upgrade in collaboration with the Rust team.
  • Colin fixed a bug in debbugs that caused incoming emails to bugs.debian.org with certain header contents to go missing.
  • Thorsten uploaded sane-airscan, which was already in experimental, to unstable.
  • Thorsten created a script to automate the upload of new upstream versions of foomatic-db. The database contains information about printers and regularly gets an update. Now it is possible to keep the package more up to date in Debian.
  • Stefano prepared updates to almost all of his packages that had new versions waiting to upload to unstable. (beautifulsoup4, hatch-vcs, mkdocs-macros-plugin, pypy3, python-authlib, python-cffi, python-mitogen, python-pip, python-pipx, python-progress, python-truststore, python-virtualenv, re2, snowball, soupsieve).
  • Stefano uploaded two new python3.13 point releases to unstable.
  • Stefano updated distro-info-data in stable releases, to document the trixie release and expected EoL dates.
  • Stefano did some debian.social sysadmin work (keeping up quotas with growing databases and filesystems).
  • Stefano supported the Debian treasurers in processing some of the DebConf 25 reimbursements.
  • Lucas uploaded ruby3.4 to experimental. It was already approved by FTP masters.
  • Lucas uploaded ruby-defaults to experimental to add support for ruby3.4. It will allow us to start triggering test rebuilds and catch any FTBFS with ruby3.4.
  • Lucas did some administrative work for Google Summer of Code (GSoC) and replied to some queries from mentors and students.
  • Anupa helped to organize release parties for Debian 13 and Debian Day events.
  • Anupa did the live coverage for the Debian 13 release and prepared the Bits post for the release announcement and 32nd Debian Day as part of the Debian Publicity team.
  • Anupa attended a Debian Day event organized by FOSS club SSET as a speaker.

Evolution of the situation In August, we released 27 DLAs. The month of August marked the release of Debian 13 (codename trixie ). This is worth noting because it brought with it the return of the customary fast development pace of Debian unstable, which included several contributions from LTS Team members. More on that below. Of the many security updates which were published (and a few non-security updates as well), some notable ones are highlighted here.
  • Notable security updates:
    • gnutls28 prepared by Adrian Bunk, fixes several potential denial of service vulnerabilities
    • apache2, prepared by Bastien Roucari s, fixes several vulnerabilities including a potential denial of service and SSL/TLS-related access control
    • mbedtls (original update, regression update) prepared by Andrej Shadura, fixes several potential denial of service and information disclosure vulnerabilities
    • openjdk-17, prepared by Emilio Pozuelo Monfort, fixes several vulnerabilities which could result in denial of service, information disclosure or weakened TLS connections
  • Notable non-security updates:
    • distro-info-data, prepared by Stefano Rivera, adds information concerning future Debian and Ubuntu releases
    • ca-certificates-java, prepared by Bastien Roucari s, fixes some bugs which could disrupt future updates
The LTS Team continues to welcome the collaboration of maintainers from across the Debian community. The contributions of maintainers from outside the LTS Team include: postgresql-13 (Christoph Berg), sope (Jordi Mallach), thunderbird (Carsten Schoenert), and iperf3 (Roberto Lumbreras). Finally, LTS Team members also contributed updates of the following packages:
  • redis (to stable), prepared by Chris Lamb

Thorsten Alteholz: My Debian Activities in August 2025

Debian LTS This was my hundred-thirty-fourth month that I did some work for the Debian LTS initiative, started by Raphael Hertzog at Freexian. During my allocated time I uploaded or worked on: I also continued my work on suricata and could backport all patches. Now I have to do some tests with the package. I also started to work on an openafs regression and attended the monthly LTS/ELTS meeting. Debian ELTS This month was the eighty-fifth ELTS month. During my allocated time I uploaded or worked on: I could also mark the CVEs of libcoap as not-affected. I also attended the monthly LTS/ELTS meeting.Of course like for LTS, As suricata had been requested for Stretch as well now, I didn t not finish my work here. Debian Printing This month I uploaded a new upstream version or a bugfix version of: This work is generously funded by Freexian! Debian Astro This month I uploaded a new upstream version or a bugfix version of: Debian IoT This month I uploaded a new upstream version or a bugfix version of: Debian Mobcom This month I uploaded a new upstream version or a bugfix version of: misc This month I uploaded a new upstream version or a bugfix version of: On my fight against outdated RFPs, I closed 31 of them in August. FTP master Yeah, Trixie has been released, the tired bones need to be awaken again :-). This month I accepted 203 and rejected 18 packages. The overall number of packages that got accepted was 243.

Registration is open until 20th September 2025, and we are very much looking forward to seeing many readers of these reports there!

Reproducible Builds and live-bootstrap at WHY2025 WHY2025 (What Hackers Yearn) is a nonprofit outdoors hacker camp that takes place in Geestmerambacht in the Netherlands (approximately 40km north of Amsterdam). The event is organised for and by volunteers from the worldwide hacker community, and knowledge sharing, technological advancement, experimentation, connecting with your hacker peers, forging friendships and hacking are at the core of this event . At this year s event, Frans Faase gave a talk on live-bootstrap, an attempt to provide a reproducible, automatic, complete end-to-end bootstrap from a minimal number of binary seeds to a supported fully functioning operating system . Frans talk is available to watch on video and his slides are available as well.

DALEQ Explainable Equivalence for Java Bytecode Jens Dietrich of the Victoria University of Wellington, New Zealand and Behnaz Hassanshahi of Oracle Labs, Australia published an article this month entitled DALEQ Explainable Equivalence for Java Bytecode which explores the options and difficulties when Java binaries are not identical despite being from the same sources, and what avenues are available for proving equivalence despite the lack of bitwise correlation:
[Java] binaries are often not bitwise identical; however, in most cases, the differences can be attributed to variations in the build environment, and the binaries can still be considered equivalent. Establishing such equivalence, however, is a labor-intensive and error-prone process.
Jens and Behnaz therefore propose a tool called DALEQ, which:
disassembles Java byte code into a relational database, and can normalise this database by applying Datalog rules. Those databases can then be used to infer equivalence between two classes. Notably, equivalence statements are accompanied with Datalog proofs recording the normalisation process. We demonstrate the impact of DALEQ in an industrial context through a large-scale evaluation involving 2,714 pairs of jars, comprising 265,690 class pairs. In this evaluation, DALEQ is compared to two existing bytecode transformation tools. Our findings reveal a significant reduction in the manual effort required to assess non-bitwise equivalent artifacts, which would otherwise demand intensive human inspection. Furthermore, the results show that DALEQ outperforms existing tools by identifying more artifacts rebuilt from the same code as equivalent, even when no behavioral differences are present.
Jens also posted this news to our mailing list.

Reproducibility regression identifies issue with AppArmor security policies Tails developer intrigeri has tracked and followed a reproducibility regression in the generation of AppArmor policy caches, and has identified an issue with the 4.1.0 version of AppArmor. Although initially tracked on the Tails issue tracker, intrigeri filed an issue on the upstream bug tracker. AppArmor developer John Johansen replied, confirming that they can reproduce the issue and went to work on a draft patch. Through this, John revealed that it was caused by an actual underlying security bug in AppArmor that is to say, it resulted in permissions not (always) matching what the policy intends and, crucially, not merely a cache reproducibility issue. Work on the fix is ongoing at time of writing.

Rust toolchain fixes Rust Clippy is a linting tool for the Rust programming language. It provides a collection of lints (rules) designed to identify common mistakes, stylistic issues, potential performance problems and unidiomatic code patterns in Rust projects. This month, however, Sosth ne Gu don filed a new issue in the GitHub requesting a new check that would lint against non deterministic operations in proc-macros, such as iterating over a HashMap .

Distribution work In Debian this month: Lastly, Bernhard M. Wiedemann posted another openSUSE monthly update for their work there.

diffoscope diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues. This month, Chris Lamb made the following changes, including preparing and uploading versions, 303, 304 and 305 to Debian:
  • Improvements:
    • Use sed(1) backreferences when generating debian/tests/control to avoid duplicating ourselves. [ ]
    • Move from a mono-utils dependency to versioned mono-devel mono-utils dependency, taking care to maintain the [!riscv64] architecture restriction. [ ]
    • Use sed over awk to avoid mangling dependency lines containing = (equals) symbols such as version restrictions. [ ]
  • Bug fixes:
    • Fix a test after the upload of systemd-ukify version 258~rc3. [ ]
    • Ensure that Java class files are named .class on the filesystem before passing them to javap(1). [ ]
    • Do not run jsondiff on files over 100KiB as the algorithm runs in O(n^2) time. [ ]
    • Don t check for PyPDF version 3 specifically; check for >= 3. [ ]
  • Misc:
    • Update copyright years. [ ][ ]
In addition, Martin Joerg fixed an issue with the HTML presenter to avoid crash when page limit is None [ ] and Zbigniew J drzejewski-Szmek fixed compatibility with RPM 6 [ ]. Lastly, John Sirois fixed a missing requests dependency in the trydiffoscope tool. [ ]

Website updates Once again, there were a number of improvements made to our website this month including:

  • Jochen Sprickerhof made a huge number of improvements to the reproduce.debian.net statistics calculation [ ][ ][ ][ ][ ][ ] as well as to the reproduce.debian.net service more generally [ ][ ][ ][ ][ ][ ][ ][ ].
  • Mattia Rizzolo performed a lot of work migrating scripts to SQLAlchemy version 2.0 [ ][ ][ ][ ][ ][ ] in addition to making some changes to the way openSUSE reproducibility tests are handled internally. [ ]
  • Lastly, Roland Clobus updated the Debian Live packages after the release of Debian trixie. [ ][ ]

Upstream patches The Reproducible Builds project detects, dissects and attempts to fix as many currently-unreproducible packages as possible. We endeavour to send all of our patches upstream where appropriate. This month, we wrote a large number of such patches, including:
